        Generally speaking, it is far more difficult to machine Stainless steels than ordinary steels. This is especially so with austenitic stainless containing nickel and chromium.
        Our free-cutting wires are made of special grades of Stainless steel which have improved machinability and yet retain high resistance to corrosion.

• CHARACTERISTICS
          For specific work requirements, our free-cutting wire of Stainless steel must be selected taking such factors into Consideration as fatigue, usage, strength, corrosion resistance, Impact resistance etc.

    • Type 303
       Sulfur (S) is added by about 0.15 to .035% to Improve machinability.
     • Type 303 Cu
       Compound free-cutting wire steel excelling particularly in machinability with improved corrosion resistance.
